Parkinson's disease is characterized by increased reaction times in both voluntary and involuntary motor responses and often results in unintended oscillatory motion of body parts, termed as Parkinsonian tremor. A simple and efficient method for diagnosing Parkinson's disease is still not available and furthermore, on the correct diagnosis of Parkinson's(More)
Parkinson’s disease, an idiopathic and degenerative disorder of the central nervous system, is characterized by increased reaction times (by as much as 0.1 sec) in voluntary movements and often results in among other symptoms unintended tremulous (oscillatory) motion of body parts not in action, termed as Parkinsonian tremor. There are however no definitive(More)
Parkinson’s disease (PD) is a neurodegenerative disorder and patients suffering from PD experience a variety of biomechanical symptoms including tremors, stooping, rigidity, and gait instability. PD is also characterized by a permanent increase in response time in both voluntary and involuntary motor responses. Although the deterioration in biomechanical(More)
There have been recent efforts [1, 2] to understand the mechanism causing tremors at rest in patients suffering from Parkinson’s disease, from a control-systems perspective. From these efforts, it appears that one of the primary causes behind the tremors may be the increased sensorimotor loop delay in Parkinson’s patients. This increased sensorimotor loop(More)
